摘要:

背景:血管内栓塞材料相继产出并应用于临床,在应用中不断出现新问题,对栓塞材料也不断提出新要求。

目的:回顾性分析各类栓塞材料的应用及其优缺点,探讨其应用领域与栓塞材料的选择之间的相关性,为临床治疗提供参考。

方法:检索中国知网和PubMed数据库中相关文献资料,结合有关栓塞材料临床应用及实验研究的文献进行了系统评价。包括各种栓塞材料的栓塞机制、优缺点及临床应用状况,并指出了目前研究中存在的问题,展望了未来研究的发展方向及临床的应用前景。

结果与结论:栓塞材料应具有生物可降解性和生物可相容性。目前,临床使用的栓塞材料有可吸收明胶海绵、聚乙烯醇颗粒栓塞剂、微弹簧圈以及液体栓塞材料,明胶栓塞材料优点在于无抗原性、组织相容性好、取材制备方便有优良的可压缩性和遇水再膨胀性。聚乙烯醇颗粒是一种高分子材料,不溶于水,膨胀系数高,机械式栓塞血管,无致敏反应,无全身急性毒性,无皮内刺激反应,使用安全有效。液体栓塞材料中黏附性液体栓塞材料不具有血管毒性,得到了广泛的应用。血管内栓塞材料相继产出并应用于临床,在应用中不断出现新问题,对栓塞材料也不断提出新要求。因此,各种栓塞材料均有各自的优缺点,没有一种栓塞材料能适用于所有病变,选择合适的栓塞材料对安全有效的治疗非常重要。

Abstract:

BACKGROUND: Endovascular embolization materials have been produced and used clinically, but new problems constantly occur in the clinical application and new demands are also developed for embolic materials.
OBJECTIVE: To retrospectively analyze the advantages and disadvantages of various types of embolic materials and to investigate the relationship between application fields and selection of embolic materials, thereby providing a reference for clinical treatment.
METHODS: CNKI and PubMed databases were retrieved for relevant literature, and then embolic materials were systemically reviewed based on relevant clinical application and basic research literature in the following aspects: embolism mechanisms, clinical applications, advantages and disadvantages of various embolic materials. In this review, the existing problems in the current study were pointed out, and the development direction of relevant research and clinical application were also prospected.
RESULTS AND CONCLUSION: Embolic materials should have biodegradability and biocompatibility. Current embolic materials include absorbable gelatin sponge, Polyvinylalcohol embolic agent, micro-coils and liquid embolic materials. Gelatin embolic material has no antigenicity and good histocompatibility, as well as has 
excellent compressibility and water re-expansibility. Polyvinylalcohol particles are a polymer material that is insoluble in water, has high expansion coefficient, mechanical embolization, non-allergenic reaction, no acute systemic toxicity, no intracutaneous irritation, and can be used safely and effectively. Adhesive liquid embolic material has no vascular toxicity and has been widely used. Endovascular embolization materials have been produced in succession, and meanwhile, new problems in clinical applications have been found and new demands for embolic materials have been put forward continuously. Thus, a variety of embolic materials have their own advantages and disadvantages, and none of embolic materials can be applied to all diseases. To select an appropriate embolic material is very important for safe and effective treatment.
